As many of you (and some of us) come from a Windows Mobile background, you're likely used to seeing new and unreleased ROMs stripped off HTC phones spread into the wild. Such is the case with Android 2.1, aka Flan, which was ripped off the infamous Nexus One and is making the rounds on the likes of XDA Developers and elsewhere.

The ROM itself isn't up and running -- yet -- on other devices, but the boot animation apparently works just fine on the Motorola Droid, which is what we see above. [via Nexus One blog] And after the break, a closer look at the animation sequence. Visually striking, to say the least.

And when a ROM is ripped, so are its wallpaper and ringtones, which are available for all. You can snag them here.
